Claims.

My invention relates to a sprinkling device, more particularly for usein connection with stationary water outlet conductors positioned inlawns, yards or the like and the objects of my invention are:

First, to provide a device of this class which may be so arranged thatthe pattern of spray may be varied to cover a rectangular or odd shapedplot of ground;

Second, to provide a sprinkling device of this class having a novelcombination atomizing and spray directing wheel;

Third, to provide a sprinkling device of this class in which cam meansis provided for use in controlling the spray and limiting the same to arectangular or other odd shaped plot of ground or plot of ground varyingin size which may be accomplished by simple adjustment of the cammember;

Fourth, to provide a sprinkling device of this class which issues finemisty droplets of water both suitable for the watering of plants,flowers and shrubbery to promote the proper growth of the same;

Fifth, to provide a sprinkling device of this class which is verypositive and dependable in operation; and

Sixth, to provide a sprinkling device of this class which is verysuitable and economical of construction, efficient in its action andwhich will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactersof reference thereon forming a part of this application in which:

Figure 1 is a top or plan view of the sprinkling deviceand Fig. 2 is aside elevational view of the sprinkling device showing portions brokenaway and in section to facilitate the illustration.

Similar characteris of reference refer to similar parts and portionsthroughout the several views of the drawings:

The water outlet coupling l, stationary cam 2, traversing arm 3, nozzlemember 4, distributor wheel 5 and the lever B- constitute the principalparts and portions of my sprinkling device.

The stationary water outlet coupling I may be connected with theconventional water vertical pipe or any other hollow tubular conductor.This stationary water coupling I is substantially conthe stationarycoupling ventional in form and is maintained in stationary uprightposition substantially in the middle of the lawn, garden or plot ofground and the stationary cam 2 is connected in concentric rotatablyvertically adjustable relation with the coupling I by means of the nutlb screw-threaded on the coupling I and engaging one side of saidstationary cam 2, operating as a lock nut as shown best in Fig. 2 of thedrawings.

The upper edge of this cam portion 2 is provided with elevated portions2a and recess portions 212 about its peripheral edge. The stationary cam2 is rigidly secured to the coupling member so that it cannot rotatemember I, all as shown best in Fig. 2 of the drawings. The traversingarm 3 is a hollow tubular arm and is revolubly mounted over thestationary cam 2, all as shown best in Fig. 2 of the drawings. Thesleeve 3a is screw threaded to the hub of the arm 3 and is revolublymounted in the coupling l.

Positioned at the lower end of the sleeve 3a is a gasket 3b which formsa passing packing sleeve for water passing upwardly, as indicated byarrows in Fig. 2 of the drawings through the tubular sleeve 3a and intothe traversing arm 3 toward the nozzle 4. Secured on the jet end of thetraversing arm 3 is a bracket 5d and a nozzle is connected to the saidend of the traversing arm 3.

Pivotally mounted on the downwardly extending portion of the bracket 511is the shaft 5b journalled on the pin 50. Rotatably mounted on the shaft5b is the distributor wheel 5 which is provided with notches 511 on itslower side which notches extend radially to the periphery of the thedistributor wheel 5.

Rigidly connected to the shaft 5b is the lever B which engages the camportions 2a and 2b of the stationary cam 2. As shown in Fig. 1 of thedrawings this lever 6 is curved and contacts the stationary cam 2 at aposition which is parallel to the radial disposition of the traversingarm 3.-

stantially as follows: When this sprinkling device is positioned insubstantially the middle of a plot of ground, garden or lawn, waterenters l, passes upwardly through the sleeve 3a and into the traversingarm 3 toward the nozzle 4. The water jet issuing from the nozzle 4impinges on the notch portion 5a at the periphery of the distributorwheel 5 atomizing the water and causing a fine spray to be issuedradially from the axis of the sleeve 3a. It will be here noted that oneside of each of the notches 5a of the distributor wheel 5 are atsubstantially right angles to the axis of the jet issued by the nozzle 4which causes the distributor Wheel 5 to rotate about the shaft 51).

During the operation of the distributor wheel 5 and the nozzle 4 aswater is issued therefrom, the torque created by impingement of water onthe wheel 5 outwardly of the axis thereof causes the traversing arm 3 torotate in the direction as indicated by arrows in Fig. 1" of thedrawings. The lever B in connection with the shaft 5?) pivotally mountedon the pin in connection with the bracket 5d traverses the stationarycam I 2, engaging the elevated and recessed cam portions 2a and 23;causin intermittent tilted relationship of the shaft 5h together withthe distributor wheel 5 which changes the elevation of the spray issuedfrom the periphery of the distributor wheel 5.

The recessed cam portions 212 permit the downward gravitational travelof the lever 6 tilting the upper end of the shaft 3?) inwardly towardthe axis of the traversing arm 3 elevating the angle of departure of thespray issued from the periphery of the distributing wheel but therecessed cam portions 21)- provide means for elevating the spray to anangle of departure which will carry said spray to the corners of arectangular slot. Thus, the shape of the cam member 2 dictates asubstantially square spray pattern. This cam 2 may be adjustedvertically by means of the nut lb for extending or decreasing theoverall dimension of the rectangular pattern of spray issued from thedistributor wheel 5. I

It will be noted that the cam 2 may be provided in other forms in orderto control a spray pattern adaptable to various shaped plots of ground.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions I do not wish to be limited to theparticular construction, combination and arrangement, but desire toinclude in the scope of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
